ESR series service routers.ESR-Series. User manual
Create a default route by specifying the IP address of R1 router gi1/0/2 interface (192.168.100.1) as a 
nexthop:
esr(config)# ip route 0.0.0.0/0 192.168.100.1
To check the routing table the following command can be used:
11.3  RIP configuration
RIP is a distance-vector dynamic routing protocol that uses hop count as a routing metric. The maximum 
amount of hops allowed for RIP is 15. By default, each RIP router transmits full routing table into the network 
every 30 seconds. RIP operates at 3rd level of TCP/IP stack via UDP port 520.
11.3.1  Configuration algorithm
Step Description Command Keys
1 Configure RIP precedence for the main 
routing table (optional).
esr(config)# ip protocols rip 
preference <VALUE>
<VALUE> – protocol 
precedence, takes values in the 
range of [1..255].
Default value: RIP (100).
2 Configure RIP routing tables capacity 
(optional).
esr(config)# ip protocols rip max-
routes <VALUE>
<VALUE> – amount of RIP 
routes in the routing table, 
takes values in the range 
of[ 1..10000];
Default value:
10000.
3 Create IP subnets lists that will be used 
for further filtration of advertised and 
received IP routes.
esr(config)# ip prefix-list <NAME> <NAME> – name of a subnet 
list being configured, set by the 
string of up to 31 characters.
